CygnusEd uses smooth scrolling. You can set the number of pixels it moves each
scroll tick in one of the environment menus (File settings->set scroll jump).
It is very fast and very nice. Bruce used some custom blitter code that for
some reason prevented serial communication from occuring while the scrolling is
going on, (and if you were doing a download while you scrolled you aborted the
download), so he also added in a feature so that you can force Ced to use the
ScrollRaster() routine which doesn't have this problem.
